I did not know what a heeldo was until this day

I am...... not sure....

if I'm disappointing I didn't know before or horrified that I know now.

A heeldo is a harness for your heel so you can attach a dildo to it.

The more you know

...why

wat

You gotta be flexible to self fuck as it suggests

LOL

Oh

I. Did not know this.

Would be cool for foot fetishes and I suppose more comfortable than trying to put it on your toes.

Unless its like a platform boot or something... but that gets into some other kinks.
